Title: Improvements in evaporating methods and apparatus
Inventor: JENSEN ERIK
IPC: B01D1/22
Filed: 1965-03-16
Abstract: 1,094,932. Film-type evaporators; concentrating solutions. NOVO TERAPEUTISK LABORATORIUM A/S. March 16, 1965 [March 17, 1964], No. 11023/65. Heading BIB. Liquid is evaporated from a solution in a casing 10 under vacuum by supplying the solution through inlet 40 to a pool of the solution in trough 39, in the lower part of the casing, from which the solution is sprayed, by buckets 51 on rotor 46, along the outer surface of a horizontally - mounted, rotating, internallyheated cylindrical drum 28 provided with longitudinal corrugations 38. Some of the liquid evaporates from the film of solution on the sides of the corrugations on the rotating drum 28, and the residual solution drips back into trough 39. As. the solution moves along the trough in the direction away from inlet 40, the solution is several times sprayed onto the surface of the drum and it becomes increas-. ingly concentrated. The concentrated product is withdrawn through one or more of the outlets 41 to 45. Ribs 55 prevent splashing of the solution in an axial direction. The vapour evolved from the film of solution flows through droplet separator 13b into chamber 13. Some of the vapour is drawn from one end of chamber 13 into an injection condenser (not shown) connected to a vacuum pump, and the remainder of the vapour is drawn from the other end of the chamber into a jet-type compressor operated by steam. The compressed mixture of steam, solvent-vapour and air is conducted into the left-hand end of the drum 28, which is provided with a truncated conical insert 52. The compressed vapour mixture flows into the space between the insert 52 and the drum, and is gradually condensed giving up heat to the film of solution on the outer surface of the drum. The less volatile components condense first. The condensate collects in channels 56 which lead to two (or more) outlet pipes 58, 59 which are longitudinallyspaced from each other. A fractionation of solvents can therefore be achieved. Air and residual vapour is drawn through slots 63 into a pipe (not shown) leading to the injection condenser. The supply of solution to inlet 40 can be controlled, by a float chamber connected to trough 39, in order to maintain the "evaporation ratio" substantially constant. The jet compressor may be operated by the vapour of a liquid which is the same as that being evaporated in the casing 10. The jet compressor may be replaced by a mechanical compressor. The surface of the drum, at the outlet end of the apparatus, may be smooth. The concentration of a solution of insulin in alcohol and water is described; the concentrate being withdrawn through five longitudinally spaced outlet pipes. The concentrate removed from the two pipes most remote from the feed inlet end of the apparatus were free from alcohol. The concentration of an aqueous solution of trypsin is also described.

Title: An improved directly driven slewing gear for drag line excavators
IPC: E02F9/12
Filed: 1924-05-09
Abstract: 231,032. Lobnitz & Co., Ltd., and Bedgood, H. O. May 9, 1924. Scraping - apparatus.- In slewing gear for dragline excavators of the type wherein a slewing engine drives directly a vertical shaft carrying a pinion gearing with a circular rack on the stationary main-frame of the machine, the slewing gear comprises sleeve and scroll reversing gear on the driving shaft, a slide valve for regulating the steam supply to the engine interconnected with the reversing gear and a steam-hydraulic reversing engine, all of which are adapted to be controlled' by a single control. The underframe 1 carries the circular rack 2 gearing with a slewing pinion 7 which is mounted on a vertical shaft 6 passing through the turntable 4 at the point of intersection of the tables of two cylinders 5. Rods 9 are secured to the cylinders and serve as bearings for the shaft 6 and as guides for the piston crossheads 10, the connecting rods 11 taking on a crank 12. The strap of the eccentric sheave 13 is connected by rods 15 to each of the cylinders and reversal of the engine is effected by turning the sheave 13 round the shaft 6 by the gearing shown in Fig. 3. A sleeve 17 surrounds and engages a helical part of the shaft 6 and also engages, by a key 19 and keyway, a sleeve on the sheave 13, the bushing of the upper rod 9 being extended at 20 to receive them. Flanges in the sleeve 17 are engaged by a fork 21 that is fulcrummed at 22a and operated by a reversing engine 23, the fork being also connected with the valve 24 in the supply pipe 25 of the cylinders 5. The valve 24 is closed in its mid position and open in its outer positions. Links 26 and handle 27 control the reversing engine 23 causing the fork 21 to rise or fall and rotate the sheave 13 according to the direction in which the jib is to be slewed. Rotation of the shaft 6 tends to impart a vertical thrust on the sleeve 17, which thrust is taken by the engine 23 and is either diminished or reversed to cause reversal of the slewing. To stop, the sleeve 17 is moved to central position by altering the pressure in the engine 23, thereby shutting the valve 24. The engine 23 preferably comprises a steam cylinder operating a piston rod passing through a hydraulic cylinder.

Title: Arch manufacturing process
IPC: E06B1/00
Filed: 1977-03-17
Abstract: A metal profile is prebent, as a template, to the desired radius of the semicircular arch to be produced and is inserted into a plastic hollow profile which has been heated in a liquid bath to a temperature within the thermoelastic range of the plastic. The metal profile serves simultaneously as forming means and as template. After the forming, cooling to room temperature is carried out in stages. The metal profile can then be removed from the hollow profile or left in it as reinforcement. The forming takes place in a bath contained in a liquid tank (2) which is equipped with a temperature control device (21, 22) for the liquid and is allocated to a work table (1) with a flat work surface inclined on one side in such a manner that the liquid draining off is led back into the tank (2). This process makes possible the production of dimensionally accurate and durable semicircular arches from plastic hollow profiles. <IMAGE>
